Ankle brachial index (ABI) studies uses an ultrasound Doppler to diagnose peripheral arterial disease (PAD). It uses the pulse measurement from the arteries of the arm (upper limb) and the ankle (lower limb) and compares them to assess your vasculature.

A bone density test uses X-rays to determine whether you have osteoporosis or are at risk of developing osteoporosis. It measures how much calcium is in your bones. The more calcium you have, the denser and stronger your bones are. Learn more about bone density scans (DEXA).

Cardiac PET scans measure blood flow to the heart and are used to detect and diagnose coronary heart disease. Learn more about cardiac PET scans.

Continuous glucose monitoring is a device that records blood sugar levels 24 hours a day for 3 consecutive days. It can help identify fluctuations and trends that would otherwise go undetected with standard HbA1c tests and intermittent finger stick measurements. Your doctor will review the data gathered by the device and make any necessary adjustments in your diabetes management plan.

An echocardiogram is a Doppler ultrasound of the heart that evaluates heart function. Echocardiograms are also referred to as transthoracic echocardiogram (TTE), Doppler ultrasound of the heart, or surface echo.

Learn more about echocardiograms.

Electrocardiograms (ECGs or EKGs) identify if the heart is beating normally by measuring the heart's electrical activity.

Learn more about electrocardiogram.

External counterpulsation (ECP) is a device that helps circulate blood for the treatment of ischemic heart disease (angina).

Learn more about external counterpulsation therapy.

An event or Holter monitor records the heart’s rhythm. The device is worn for a period of time to record the heart's rhythm when you are experiencing symptoms of irregular heart rhythm. Event or Holter monitors are used to help heart doctors diagnose cardiac arrhythmia.

Nuclear cardiology studies (stress testing and heart strength assessment) show images of how the heart pumps blood while it is beating. Nuclear cardiology studies help heart doctors diagnose coronary artery disease and predict the prognosis of people with heart failure.

A cardiac stress test is an electrocardiogram that evaluates how the heart works during exercise. A stress test may also be referred to as an exercise test or treadmill test.

Learn more about heart stress testing.

A vascular ultrasound shows how blood flows in the both the veins and arteries. It is used to detect if there are any areas where the veins and arteries are narrow or blocked.

A peripheral arterial ultrasound test can screen for stroke, peripheral artery disease of the legs, and aortic aneurysm, a common and potentially fatal disease. Learn more about peripheral arterial disease (PAD).

A peripheral venous ultrasound is a simple imaging assessment that creates images of veins to identify the direction of blood flow and blockages. Venous ultrasound is useful for identifying clots (deep vein thrombosis), varicose veins, and chronic venous insufficiency.

An abdominal ultrasound is an imaging procedure used to examine the internal organs of the abdomen, including the liver, gallbladder, spleen, pancreas, and kidneys, as well as the blood vessels that lead to some of these organs. It is used to diagnose the cause of abdominal pain or kidney infections, or to diagnose a hernia, kidney stones, or gallstones.

A renal ultrasound is an imaging procedure used to study the renal system, which includes the kidneys, bladder, and ureters (the tubes that connect the kidneys to the bladder). It is used to look for changes in the bladder wall, kidneys, or ureters; kidney stones or stones in the urinary tract; and blood flow to the kidneys.

A thyroid ultrasound is an imaging method used to view the thyroid, a gland in the neck that regulates metabolism. A thyroid ultrasound is usually done to diagnose a growth on the thyroid gland and determine if it is a cyst or benign or cancerous tumor. MET Testing.
